补服乳清蛋白对人体有氧运动能力的影响

摘要

This study examined the effects of supplementation whey protein, or placebo on VO2max and Aerobic Endurance, researched effects of intaking whey protein on aerobic exercise power as well. Methods : twelve healthy males who major in PE participated in this research study. Single -blind design was employed,and the experiment was finished in 6 weeks. Participants performed three times increasing the load continuous on Anaerobic power cycling which lasted for three minutes followed by consumption of 7g whey -protein, 14g whey- protein or placebo half an hour before exercise, also performed twelve minutes aerobic en- durance running followed by consumption of 7g whey -protein, 14g whey -protein or placebo. Results: There was significantly different between supplementation 7g whey - protein and placebo ( p 〈. 05 ), similarly there was very significantly different be- tween intaking 7g whey -protein and 14g whey -protein( p 〈. O1 ). There was significantly different between supplementation 7g , lgg whey - protein and placebo( p 〈. 05 ). Conclusion : supplementation different mount of whey - protein has different effects on VO2max, supplementation whey- protein before exercise may improve aerobic endurance.%研究补服不同量的乳清蛋白后人体最大吸氧量及有氧耐力的变化,探讨补服乳清蛋白对人体有氧运动能力的影响。方法：采用单盲实验法,以体育系12名健康男性大学生作为被试,分为两个阶段共六周进行试验。每个阶段补服3次不同的补剂,第一个阶段在无氧功率自行车上进行3个连续3min的递增负荷运动;第二个阶段进行12min跑的耐力运动。补服7g和14g乳清蛋白与安慰剂相比最大吸氧量水平都有不同程度的变化,补服7g,14g乳清蛋白与安慰剂相比差异性显著（p〈0.05）;机体有氧耐力水平出现显著性差异（P〈0.05）。（1）补服不同量的乳清蛋白都不同程度影响人体的最大吸氧量水平。（2）补服乳清蛋白饮料可能会提高人体的有氧耐力。
